            Bug ID: 36201
           Summary: [X86] Replace kortest intrinsic with icmp+bitcast+or
                    emitted from clang
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedb...@nondot.org
          Reporter: craig.top...@gmail.com
                CC: llvm-bugs@lists.llvm.org

Once D42772 and D42817 are commited, we should be able to directly emit KORTEST
in IR by using an vXi1 or, bitcasted to scalar, and then compare to -1 or 0
depending on whether its the C or Z builtin.
